Table 2. Impacts of biotype on the infection frequency of S-symbionts in the field populations of B. tabaci (B biotype: 17 populations, 456 adults in total; Q biotype: 44 populations, 1149 adults in total)^*.

*The frequencies in columns sharing the same upper case letter are not significantly different at P<0.05 (multiple comparisons with Bonferroni corrections). The expected (exp) co-infection frequencies of whiteflies by two or three symbionts (e.g. RH or RHC) were calculated by multiplying the infection frequencies of whiteflies by each of the two or three symbionts. The expected (exp) and observed (obs) co-infection frequencies that share the same lower case letter are not significantly different at P<0.05 (nonparametric tests χ2).
